Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed November 18, 1909. Serial No. 528.781.

To 1.1.7! 207mm it may concern:

Be it known that I. l-lizxnr It. liLLis'. a citizen of the lfnited States. residing at Salt Lake City. in the county of Salt Lake and State of Utah. have invented certain new and useful Improvements in Resilient heels, of which the following is a specification.

My invention relates to resilient wheels.

The object of the invention is to provide a wheel having inner and outer concentric members between which are resilient balls so mounted that each ball is subjected at the same time to compressing and shearing forces and each ball sustains the same weight at every point of turn of the wheel; the weight sustained by each ball. being PlOPOltiUllzttC to the number of balls in the wheel and the load applied to the wheel.

.X't'urther object is to provide in such a wheel means whereby the balls perform the above functions and also he further function of holding the two members of the wheel or tire together against lateral separation.

lhese objects I accomplish by the construction shown it; the accompanying drawing: in which 1- Figure 1 is a side elevation of a wheel containing my improvements; Fig. 2 a vertical section thereof; F g. is a side elevation of a tire removed from the wheel and containing my improvements; Fig. l is a detail section thereof; Figs. 5, G, 7 and S are details of modifications to be herein after described: Fig. 9 is a side elevation of a further modification where the brackets are not in staggered alternate relation and the wheel members are held together by chains; Fig. 10 is a section on line 10-10, of Fig. 9. Fig. 11 is a section through a further modification.

A. designates the hub. B, the spokes and C the telly of the wheel and these may be of any suitable construction and materials. The telly C, is provided at opposite sides wi h radially disposed outwardly projecting brackets. D. in staggered relation to each other and havin; concavities (Z of suitable size and form in their inner faces.

E, is the tire proper or tread having a central annular web or flange 1: on its inner side from which project inwardly. the staggered brackets E, having concavit-ies e on their inner faces. The brackets D, E. overlap and alternate on opposite sides of the wheel ing means. 'the run by transverse bolts (1", or in any and their z-oncavities register and form sockets or pockets in which are placed baits i of suitable lCflllQlllZ material. such as rubher. and these balls may be solid or hollow as desired.

Owing to the brackets of the inner and outer membc"-" of the wheel alternating. with their races.-. facing each other. the balls will hold the said members together and the centers of the balls will be in direct line with tile vertical centers of the wheel membersof course were the brackets of each member all on one side the balls could not held the members together, but by alternatingthe brackets at opposite sides. asv described. the balls alone will form the hold- The brackets l are secured to other preferred manner.

in Figs. 3 and l. the invention is shown as a tire rather than in a complete wheel. and E the tire proper or tread surface. while C, is the inner member or rim D, E. are the staggered alternating brackets. aria F the balls. The brackets are secured in place by the vertical bolts 1! extending" through lheir'basc llztllfiti. in Fig. 3 a annular elastic washer H. is placed bet ween the two brackets D". ll. to prevent the entrance of foreign matter. while in Fig. (i the outer edges of the conical l)lf(.'l\'tl. are surrounded by an elastic band (l to protect the ball from the action of foreign matter. These tires maybe shaped to lit the standard wheels: to which pneumatic tires are now applied and their treads may be studded or covered with a solid rubber tire. if desired.

In Figs. 7 and the brackets D are formed with threaded openings (1' and the concavities (Z. are formed in threaded cones or plugs D which are concave; on their inner faces for this purpose. while 31? their outer ends squared wremit-receiving projections (P, are formed. Thus the cones or plugs D may be screwed in to any desired adjustment and to retain them in their adjusted position their outer sides are provided with ribs or indentations (73 with which the free end of a spring (Z engages. By my improved construction each ball receives the same load at every point of turn of the wheel. The resiliency of the wheel is due not only to the compressing of the balls, but is largely increased by the shearing effect upon the balls. The balls hold the two members together and prevent them from rotating one on the other while allowing free yielding movement in every direction.

Broadly stated, the inner and outer memhers (I, E, of Figs. 1 and 2 and their con necting brackets and balls may be termed a the just as the members C, 15*, of the other figures, and their connecting brackets and balls constitute tires.

Referring now to Fig. 9, it will be seen that the brackets D, are all on the same side of the member C, while the brackets E, are alien the same side of member 15, the two sets of brackets being opposite each other to form the ball pockets 0. for the balls F. In

together I provide the members C E, with opposed brackets K, K,between the brackets I), E, and these brackets are connected by short chains Z', provided at their. ends which the chains may be adjusted to'hold the wheel members and their ball carrying brackets in proper relation.

In 11 is shown a mechanism which may be employed between the brackets D, E, of Fig. 1. This mechanism comprises brackets 1) E within the concavities of which is placed a rocking rod L to yieldingly spaced the members C, 15, or C, F. The rounded ends of the rods L of Fig. 11, are loosely mounted in the conical sockets in the brackets and atlord a yielding or loose connection which serve to space the wheel members.

'hat I claim is:-

1. In a wheel, two concentric members having overlapping parts provided in their neously to a compressing and shearing ac tion therein and each ball sustaining the same weight wheel.

In a wheel, two concentric members having alternating overlapping parts and individual resilient balls seated in laterally opposed pockets formed in the meeting faces of said overlapping parts and holding the two members yicldingly together.

In a wheel. inner and outer members provided with laterally opposed cup-like concavities having their axes parallel to the 3 axis of the wheel and individual rubber cushorder therefore. to retain the wheel members i ions within the pockets formed by said consl a compressing and shearing action and each cushion sustaining the same weight at every point of the wheel; said cushions with eye bolts la, having nuts if, at the; outer sides of the brackets by means of;

also cushioning the wheel members against lateral strains.

4-. In a wheel. two angular concentric members each having brackets on opposite sides alternating with each other, and pro 5 videtl with registering concavitics, resilient baits in the pockets formed by said concavs and annular guards protecting the pockets and balls.

In a resilient wheel, a pair of parallel brackets having registering threaded apertures, half sockets screwed into said apertures with their concavities facing each other, and a rubber euslnon between the sand half sockets.
